Request for critique of text on sexual strategies

Hi, I would be grateful for any critiques you can offer of the following (I'd rather not say where it came from for now, and if you know, please don't say):

Quote:

For many years, I was a research biologist. My studies in this area indicated that there are two extreme strategies for sex in the animal kingdom - with variations on the theme in between. One extreme is the philosophy of the rutting wildebeest. This is a winner-takes-all philosophy where the strongest male gets to service the females in the herd. The advantage of this strategy is that the genes for strength are the ones that get passed on to the next generation. ... The other sexual philosophy in the animal kingdom is [mating for life]. ... The strength of this approach to sex is that it allows a rapid build-up of numbers. It does so because almost every adult is engaged in sexual activity. This is advantageous when numbers need to increase quickly to take advantage of favourable conditions.

Thanks in anticipation.
